Suzie I don't know how old you are, but do you remember the Summer of 1980? Dallas had like 45-50 straight days over 100! It's ALWAYS hot in the summer in Texas, my sisters and Brother in Houston bitch about it all the time.
I remember it very well. I even went to Six Flags during the heat wave, boy was I stupid back then!!! We fried an egg on the sidewalk. It took about 25 minutes, but it cooked it!!!
